SUPPORT FOR WINDOW PANES.

Application filed February 11, 1926. Serial No. 87,706.

My invention relates to a metal window sash and more particularly to anouter clamping plate and means for connecting it to an inner clampingmember.

The object of my invention is to provide a construction whereby theouter clamping member of a metal window sash may be accuratelypositioned and held in such a manner that it may exert yielding pressureon the glass.

The construction and the minor objects of my invention will appear asthe description proceeds.

In the accompanying drawing forming a part of this specification, Fig. 1is a crosssection of a sash embodying one form of my invention; Fig. 2is fragmentary front elevation of the same, and Fig. 3 is a view similarto a portion of Fig. 1, but showing a different form of face plate.

The sash is shown as applied to a lower frame member or sill 10 whichhas a horizontal portion '11 beneath the glass sheet 9, and

' a riser 12 behind the lower edge of the glass.

This sill is shown with a sheet metal cover 13 having an upturned flange14 at its rear edge adjacent riser 12. An inner glass engaging member 15has a substantially horizontal portion 16 the front edge of which isturned down to form a flange or lip 17 adapted to contact the rear faceof the sheet of glass. At the rear edge of'horizontal portion 16 thereis a downwardly directed portion 18 adapted to rest against riser 12 andhaving an offset portion 19 at its lower edge adapted to extend downwardin front of flange 14 into contact with sill covering 13. Preferablyoffset portion 19 terminates in aforwardly directed portion 20 adaptedto lie on top of covering 13.

The outer clamping member or face plate 21 has a glass-engaging flange22 at its upper edge, and has a head 23 at its lower edge adapted torest on sill covering 13 and to abut against the forward edge of portion20 of rear plate 15. A substantially horizontal flange 24 extends frombead 23 and is raised enough to overlie portion 20 with a slight normalclearance.

A sheet metal box-shaped bracket 25 lies on one side 26, which rests onportion 20, and has its bottom perforated to receive a screw 27 by whichit and clamping plate 15 are held in place a ainst riser 12. The upperside 28055 the racket is provided with a screw-threaded bushing 29. Thefront side of the bracket is open.

A substantially L shaped member 30 has the upper end 31 of its uprightarm resting against flange 22 while its horizontal arm 32 extendsrearward into bracket 25. The angle 33 of member 30 rests upon flange24, and a portion 34 of flange 24 may be bent upward through a hole 35in arm 32.

Arm 32 is slanted upward at 36 and then has its rear end turned down at37 to rest upon side 26 of bracket 25 and support the rear end ofportion 36. Flanges 38 are preferably provided at the sides of member 30to stiffen the member and maintain its two arms at a substantiallyconstant angle.

A screw 39 is passed downward through bushing 29 and has a rounded lowerend 40 adapted to press against slanting portion 36 of arm 32 and pressthe arm downward and at the same time draw it to the rear by means ofcam action against the slanting surface.

The forward edge 41 of bracket bottom 26 is turned upward slightly, soas to furnish a yielding support for arm 32,. and flan e 24 affords ayielding support for the ang e of member 30.

Bead 23 rests upon the unyielding surface of sill covering 13, and isheld against rearward movement by portion 20 of back plate 15, while theconstruction of offset portion 19 is such that bead 23 may force portion20 slightly to the rear, this movement will not be enough to materiallychange the angle of the front plate.

It will be readily understood from the above description that, when theparts are as-- sembled in the manner disclosed, downward movement ofscrew 29 results in cam action against portion 36 and draws member 30 tothe rear and thereby brings the front plate against the glass andagainst the front edge of portion 20. Member 30 presses downward onflange 24, and this insures against bead 23 slipping over the edge ofportion 20. The slight yielding allowed by portions 19, 41 and 24 issuflicient to relieve undue strain on the glass, and at the same timethe front clamping plate is not allowed to move to an objectionableextent. The comparative rigidity of member 30 aids in preventing un'duemovement of the front clamping plate and in confinin any yielding to theplaces mentioned a ove.

In Fig. 3 an outer clamping member or face plate 21 is shown havingupper and lower flanges like those shown in Fig. 1, but having theintermediate portions extending along different lines. Parts shown 1nFig. 5 3 are designated by the same reference numerals as correspondingparts in Fig. 1. wlth the letter a added. Itwill be noted that flange24* is slightly widened, and that the upright arm of member 30 1smodified to fit within the modified face plate. These changes arewithout material effect upon the operation of the device.

While I prefer to use the portion 2Q, 1t might be omitted in some cases,and various 16 other obvious changes maybe made within the scope of theappended claims, WhlCh define my invention.
